The Biosynthesis of Ethyl-{beta}-glucoside in Extracts of Pea Seedlings 1

Tin-Yin Liu2 and Paul Castelfranco

a Department of Botany, University of California, Davis, California 95616

An enzyme, which lacks cellobiase activity, responsible for the synthesis of ethyl-{beta}-glucoside has been found in the extracts of pea hooks (1-centimeter length of the apical portion of epicotyl) and has been partially purified by ammonium sulfate fractionation. The enzyme can transfer the glucosyl moiety from a group of phenolic {beta}-glucosides to ethanol. A specific {beta}-glucosyl donor, isosuccinimide {beta}-glucoside, isolated from the extracts of pea seedlings shows the highest activity. The characteristics of the enzyme which synthesizes ethyl-{beta}-glucoside and the glucosyl donor, isosuccinimide {beta}-glucoside, have been studied. The significance of this system (enzyme and isosuccinimide {beta}-glucoside) has been discussed.
